how to make a chance table

[SavageCabage619]

so im trying to write a skript, so whenever we jump a random mob spawns.

What i am trying to do is something like:

on player jump:

    spawn {Mob}

and the {mob} will spawn one of all mobs. because I tried doing

on player jump:

    chance of _% 

        spawn _ mob

    chance of _%

        spawn _mob

and so on.

But doing that sometimes spawns multiple mobs at once and sometimes doesnt spawn mobs at all.

I suggest doing something like this:

on player jump:
  chance of 50%:
    spawn mob
	stop

  chance of 50%:
    spawn mob
	stop

  else:
    spawn mob
	stop
